Your ophthalmologist

He is the one doctor you must meet eye to eye-
that is the only way he can tell what is going awry.
He'll shine a searchlight in your eye, tell you to hold still-
because thus magnified he can tell if this body part is ill.
But he first puts you before a chart with many a letter,
they go from large to small for you to read-and you had better.
Because if the little lines give you trouble aplenty,
there is no way for you to claim 20/20 .
And that's where your eye specialist is the man to see,
when he fits you with glasses he shall earn his fee.
You can drive your car, read your paper, watch TV-
without his expertise what would your life be
You'd float in the dark, into things you would bump,
you'd be lucky if you get away with only a small lump.
One of your most precious possessions: your eyesight-
only this specialist will see that it does work alright.
